And I am planning on wiping my machine soon. I have my entire server backed up to it right now on my F3's, because my server is down for a new board, CPU, and RAM. Once I get all the data moved back to it, I'll have no choice but to format, as I've lost my entire F3 RAID array, which had programs and games installed on it (I just deleted the folders, and ignored uninstalling everything).
So I will find out soon enough. I just can't do it right now, because of data issues right now.

I just edited my post with the length.

So I am finally starting in on overclocking my 7970. I can get stable on stock volatge at 1125/1575. If I push anymore it errors in OCCT though. At those clocks I passed two 30 minute OCCT runs, four Heaven 2.5 runs, a couple 3D Mark 11 runs, and about four hours of SWTOR last night. I didnt notice any artifacting and there was no crashing, however, the 3DMark 11 scores seemed strange to me. Two were at 8500 and two were at 9000. I am pretty much a noob at this so I am not sure if that is normal or if I need to go back to checking stability some more. It seemed the fluctuations occured in the Physics and Combined tests. Should I start looking at my CPU overclock? I have been running it at its current setting for a couple weeks with no issues. I just want to make sure I have everything as stable as possible before I start adding voltage to the card. Thanks for your help!

Obviously you have Powertune set to +20%?

Yeah, I can see the product dimensions on the website. But that doesn't tell me how far its going to stick off the back of the card though.

I just picked up my Sapphire H7970 today and I'm kind of unimpressed frown.gif Maybe I should have just waited for a MSI TF3 or even Kepler...

It does stock at 1125 on the core and 1575 on the memory just fine, but it appears that it will only do 1200 on the core if I up the voltage to 1.25v - that's a bit extreme. The asic rating on GPU-Z gives it a score of 85% though. Powertune is set to +20%, and powerplay and everything is disabled.

I'm disappointed tbh, I was hoping for at least 1250 easily, yet I think I may have hit a brick wall at 1200. I'm leaving it on CCC's max OC for the time being. I was using MSI Afterburner beta 12. Perhaps the temps got too hot and the GPU just blacked out? It wouldn't pass the "dragon statue" in Heaven 2.5 when I tried anything higher than 1200 on the core.

Your unimpressed by a 200Mhz over clock on stock voltage? That's a great OC especially for NOT having to bump voltage.

The new 28nm seem to not respond so well to voltage bumps but YMMV. Your getting 275Mhz OC with voltage bump on air is awesome. No water block required. Sapphire is great and you should be very happy with that over clock in all reality. thumb.gif

I guess, but I was still hoping for a lot more since I've seen people doing a lot higher than 1200mhz on the core, and they don't even need as much voltage as I do. It's running great and I'm still happy at the end of the day.

Ah well, I guess we can all look forward to better HD7900 drivers now since they're not fully optimized and all for the new architecture smile.gif
